Hoof- 'IMPROVEMENT 1N varon-Bouwens.

he Schedule referred to in these Letters Patent and making part of the same I, JOHN C. LOVE, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an improved Vapor-Burner, of which the following is a specitication.

Nature and Object of my Invention. y My invention relates to improvements in that class of burners in which the vapors ot' light volatile 'oils are generated and burned; and

My nren tion consists of a perforated gas-generating chamber, in combination with a conducting-tube or tubes, and constructed, as fully described hereafter, so as to insure a rapid and uniform generation ot' gas, and the production of a steady and brilliant light.

Description of the Accompanying Drawing. Figure l is a sectional view of my improved vaporburner;

Figure 2, a view ofthe same, partly in section; and

Figure 3, a sectional view of a modification. All of the views are drawn to an enlarged scale.

General Description.

The burner, as represented in iig. 1, .consists of a central tube, A, and ot' a casing or vaporizlng-chamber, l, secured to and containingvthe upper end ofthe Said tube.

The sheet-metal cap f, which forms the top and sides of the chamber B, is fitted over, and brazed, or

otherwise 1 iern1anently secured to a disk, h, which' constitutes the bottom of the said chamber, the outer edge of 'this disk being bent upward, as best observed in ng. 1, so as to form an annular gutter' or channel, @which extends entirely around the burner.

In the centre of the disk h, is a short tubular projection, k, having internal screw-threads adapted to the threads k' ofthe tube A; this method of connecting the two portions oi' the burner together enabling the upper end of the tube to beextended into the chan'iber B, to any height desired;

The upper end of the tube may be curved or rounded,

" and has a small central aperture, in, for the passage oi'. the oi-l or vapor from the tube ,into the chamber B,

and, extending around the cap j, close to the bottom ot' the said chamber, is a numberof minute perforatlons, arranged at equal distances apart from each other. I

The tube A, which should be furnished with a suit- .able cock, communicates with a reservoiriarranged above the burner, `and containing a supply oi' benzine, or ot' any of the light volatile oils used for burners ot' this class. y

On opening the cock, the oilwill iilLtbe tube A, and will be' projected 4through the aperture m, ln a fine jet, into the interior of the chamber B,- it falling 'upon the disk lh, andA escaping, through the peribrations r, into the annular gutter i, which extends around the burner. y t

The film ofplL-which thus escapes into the gutter i, is ignited, and continues to burn until the burner is sufficiently heated to vaporize the oil, which passes into the chamber B, the gas or v'apor thus generated then issuing ii'om the perfoiations 'r in a number of iine jets, whiclrbecome immediatcly'ignited, and burn with a clear tlame. v

The gas-jets still further lieat'the interior of the vaporizlng-cha-mbelf and the metal of the tube A, so that the oil within lthe latter also becomes heated, or partially vaporized, before escapinginto the chamber B, and, in the latter, the vaporizing is completed, and the vapor heated and rareiied so as to increase its volume and quality, it escaping through the perforatlons r with considerable force, and inthe best condition n'burnlug. f

f The tube A, heilig screwed into the disk h, can beextended into or withdlawn from the chamber B, as described, this ad j ustablllty enabling a greater or lesser portion of the tube to be heated, and, consequently, regulating the rapidity with which the vapor can be generated, and the quantity consumed. l

Where'it is desirable to rapidly generate and highly' vheat the vapor, I introduce into the chamber B a wire spring, s, or any" equivalent to the same, which will afford an extended metallic heating-surface, with- 'outinterfering with the circulation within or passage of the vapor from the chamber.

In the modification'of my invention, shown in iig. 3, the casing or chamber B is Vof an annular form, with a central air-passage, .t, and two feeding-tubes .A A are employed, there .being also, in addition to the peifomtions rr, another row of holes at the top of the burner.

Although my invention is to be used principally for chandeliers, with a supply of oil above the burner, as be'ore mentioned, yet I de not desire to confine myself' to this use, as the burner may be employed for a portable lamp, with the supply of oil beneath, in which case the tube A must contain a wick, and be open at the top.

v v Claims. 1 claim; l

1. The generating-:chamber B, its openings lr, andplate or bottom h, curved, or inclined downward from the centre of the chamber tothe openings r, substantially as and furthe purpose described..

2. The combination ofthe vaporizing-chamber, tube or tubes extending into the same, and a series of open in gs, r, arranged directly above or on a line with the bott-om of .the chamber, as specided.

3. A coil of wire, s,or its equivalent, arranged with- `in the vaporizing-charnber, as specified..

4. The'combination of the two conducting-tubes A A, chamber B, its central tube t, upper and lower .openings 'r fr, and channel t', all arranged as described.

' In testimony whereof, I have signed my name to this specification, in the presence'ot' two subscribing witnesses. y
